Lucidchart vs Structurizr

Lucidchart is a cloud-based diagramming tool for mapping processes, planning teams, and visualizing technical systems. It supports process maps, flowcharts, organization and team planning, technical diagrams, and systems and architecture visuals. Lucid AI can use text prompts to add content to the canvas and answer questions. Users can link Google Sheets, Excel, or CSV files to create visualizations from data, and collaborate in real time or asynchronously. Its marketplace lists integrations including Jira, Confluence, Slack, Microsoft Teams, Notion, AWS, and Azure. The public API supports creating, reading, and updating Lucidchart and Lucidspark documents. The Free plan costs nothing and includes three editable Lucidchart documents, up to 60 shapes per document, and 100 basic templates. Individual costs $9 a month and adds unlimited documents, shapes, and lines, premium templates and shape libraries, Presentation Mode, 1 GB cloud storage, and Visio import and export. It is available on Android, iOS, web, and as an extension; there is no desktop app. Lucid lists a free plan and a seven-day trial.

Structurizr is a models-as-code tool for creating software architecture diagrams from one C4 model written in Structurizr DSL. A model can produce system landscape, system context, container, component, code, dynamic, deployment, custom, filtered and image views. Its C4 diagrams are interactive and animatable, can be embedded, and include an automatically generated key or legend. Users can work in a browser playground, use a local diagram viewer and layout editor, or run a self-hosted server. The CLI exports workspace views to PlantUML, Mermaid or a static HTML site; supported imports include Structurizr DSL and Structurizr JSON. Version history is available. The product has API, Linux, macOS, self-hosted, web and Windows availability. Structurizr offers a free plan and a 14-day trial. Paid server licenses start at £300/mo (annual) for 1–20 unique users per installation; higher user bands cost more. The self-hosted open core is free when built from source, but has no authentication and public workspaces. Structurizr is headquartered in Jersey, Channel Islands. Its cloud service runs in AWS US-East-1 and describes AES encryption and optional client-side encryption for paid workspaces.
